NOTES for Co1 15:28
Paul describes a lot and differently the dynamism of the revelation of the Kingdom in the world. In principle, there is nothing surprising here: because we live at the time of the Kingdom to come, Paul understands of course perfectly that and tries to bring up to the readers of his messages what he finds important to tell them on this subject. And hardly to anyone of the Christians could appear doubts on the fact that, in the dynamism of the revelation of the Kingdom, the relationships of Jesus with His Heavenly Father play a decisive role. But how thus to understand Paul's words that the Son will subdue Himself unto the Father only when the Father will subject everything to the will of the Son? Was not Jesus absolutely subjected to the will of the Father from the beginning? But all the same we cannot speak about a complete subordination of man to God before the total transformation of the human nature.
And here it is already not important if this nature is damaged by the original sin, or not. Even if the humanity had in its history such a sad page as the fall, transformation would always be necessary for the human nature in order to enter the Kingdom. And if that was the case, then until the return of the Savior and the triumph of the Kingdom, it does not come to speak about God's full power over man; it remains a certain gap, that the non transformed nature is not able to overcome.
But even if it was the case, indeed, all this should not concern the Savior Himself: because He is Risen already in a transformed body! His humanity already from the moment of the resurrection was in nothing against His will, and if before the resurrection He could get again tired or feel pain, then after the resurrection it was already impossible. And nevertheless: indeed, His life is inseparable of the fullness of the Kingdom, which He carries in him and gives the world through the Church. And paradoxical as it may sound, the fullness of His transformation depends on the completeness of the transformation of the world and humanity; it is connected to them, as the head with the body.
Paul indeed does not call allegorically and symbolically the Church the body of Christ: the transformation of His human nature will not end as long as will not be transformed whoever is connected to him by spiritual relations, relations of the love, which penetrated into the Kingdom. But the breath of the Kingdom is the breath of the Father entering the world through the Son, through this Kingdom, which the Son brought to the world. And the Father, acting in the world through the Son, brings Him closer to Himself. So that in the end of time God becomes "all in all".
